Nipple penetration/Cum based breast expansion,

Calbee 6 years ago in Fetishes and Sex Toys updated by Dongus Rex 3 years ago 1

The ability to insert penis/finger into nipple.

Cumming while inserted causes breast to inflate.

Super simple.


Alternatively a toy could be added to milk cum from a subject, then inject it into another's breast/ass/vagina, and inflate that way.

Yeah, this is a feature I'd like to see.
